Have you tried this old wives tale

My son is teething and to me baby oral gel not really giving him relief and the diapers don't even get me started. The old lady across the street told me to take an egg (not cooked), write my son full name around it and put it in a soak and nail it to his bedroom doorway. Have anyone ever heard or tried this because right now I would try about anything but this old lady is also the same lady that told me wipe my son face and with his first morning pee diaper so I think she a bit batty. I keep thinking wouldn't the egg go bad and how does this work?
